Question

A trolley goin down an inclined plane , has an acceleration of 2cm-2 . what will be its velocity 3s after the start?

Answer 1

Answer:

we can do this problem with the first equation of motion.

Explanation:

v=u+at

here,a=2cm^-2,initial velocity =0 as it starts from rest,time=3s.

substituting the values in the equation, we get..

v=0+2*3

v=0+6

v=6cm/s.

Hope it helps..

pls mark me as brainiest..

Answer 2

Explanation:

v=u+at

v=0+0.02*3

v=0.06m/s

or

v=6cm/s
